SOME OBSERVATION ON INTERACTIONS OF RAYLEIGH WAVES IN AN ELASTIC SOLID MEDIUM WITH THE GRAVITY FIELD.

The object of this paper is to investigate the effect of gravity on Rayleigh wave propagation in a homogeneous isotropic elastic solid medium. Under the assumption that the force of gravity creates a type of initial stress hydrostatic in nature, the classical equations of motion for the elastic waves propagation in a homogeneous isotropic elastic solid medium have been modified by Biot's theory of initial stress.
